DMFieldShellEvaluateFEDefault#

Default finite-element evaluation for a DMFIELDSHELL that maps the quadrature points to real space using the coordinate DMField and then calls DMFieldEvaluate().

Synopsis#

#include "petscdmfield.h" 
PetscErrorCode DMFieldShellEvaluateFEDefault(DMField field, IS pointIS, PetscQuadrature quad, PetscDataType type, void *B, void *D, void *H)

Not Collective

Input Parameters#

field - the DMField of type DMFIELDSHELL
pointIS - the IS of mesh points at which to evaluate
quad - the reference-element quadrature
type - PETSC_SCALAR or PETSC_REAL

Output Parameters#

B - values at quadrature points, or NULL
D - derivatives at quadrature points, or NULL
H - Hessians at quadrature points, or NULL

Note#

Intended to be registered as the FE evaluation callback via DMFieldShellSetEvaluateFE() when the shell only supplies a bulk DMFieldEvaluate() implementation.
